Here is a concise summary of U.S. Patent 11,806,120.

Title: Health risk indicator determination

Assignee: Beijing Shunyuan Kaihua Technology Co Ltd

Inventors: Ulrik Wisløff, Christian Ragnar Gutvik

Issue Date: November 7, 2023

Abstract:
A method and apparatus for determining health risk for a user are described. The method involves obtaining heart rate values and motion information of the user over a monitoring period. The heart rate values are sampled at a variable rate based on a comparison of previous heart rate measurements to the user's heart rate range (the difference between their maximum and resting heart rate). An expected heart rate level is determined based on the user's motion. An aggregate heartbeat value is then calculated by weighing the heart rate values based on both the motion information and a comparison with the expected heart rate. Finally, a health-predictive activity score is determined from this aggregate value.

Plain-Language Overview of Independent Claims:

Claim 1: A method for determining a user's health risk by:

• Collecting both heart rate data and motion data over a period of time. The rate at which heart rate is measured changes based on the user's previous heart rate readings compared to their overall heart rate range.
• Figuring out what the user's heart rate should be based on their movement.
• Calculating a total "heartbeat value" by giving more or less weight to the collected heart rate data, depending on both the user's motion and how their actual heart rate compares to the expected heart rate.
• Using this total value to determine a score that predicts health-related activity.

Claim 9: An apparatus (such as a device) for determining a user's health risk, which includes a processor and memory. The device is programmed to:

• Gather heart rate and motion information over time, adjusting the heart rate sampling frequency based on past readings.
• Establish an expected heart rate based on the detected motion.
• Compute an overall "heartbeat value" by weighting the recorded heart rate data based on the motion and a comparison to the expected heart rate.
• Calculate a health-predictive activity score from this overall value.

Claim 17: A non-transitory computer-readable storage medium (like a memory chip) that contains instructions for a processor to:

• Obtain a user's heart rate and motion data over a monitoring period, where the heart rate sampling rate is adjusted based on a comparison of a previous heart rate measurement to the user's heart rate range.
• Determine an expected heart rate level from the motion data.
• Calculate an aggregate heartbeat value by weighting the heart rate values based on both the motion information and a comparison of the actual heart rate with the expected level.
• Determine a health-predictive activity score from this aggregate value.

A search of the CAFC (Court of Appeals for the Federal Circuit) dockets for 2026 did not reveal any cases specifically citing US Patent 11,806,120. However, the absence of a result does not definitively mean no litigation exists, as cases could be filed under different names or may not yet be indexed.
